The purpose of this study was to develop a scale to evaluate stress in elderly patients with coronary artery diseases (CAD) and to examine validity and reliability of the scale.
The development process for the preliminary scale included construction of a conceptual framework and initial items, verification of content analysis, sentence correction, and pilot study. This study was conducted using a questionnaire survey with one-to-one interviews during January and February, 2012. Participants were 240 elderly patients with CAD. Data were analyzed using item analysis, factor analysis, criterion related validity, and internal consistency.
The developed scale consisted of 32 items and 6 factors - aging and disease (7 items), family relations (5 items), anxiety and withdrawal (9 items), management of daily living (3 items), compliance of medical regimen (4 items), poverty and finance (4 items), and explained 68.5% of total variance. The scale had significantly positive correlation with the Korean Perceived Stress Scale (KPSS). Cronbach's alpha was .96, and Guttman split half coefficient was .91.
Results indicate that the Stress Scale for Elderly Patients with CAD has validity and reliability, and is a suitable scale in health care settings to assess stress in elderly patients with CAD.
本研究旨在开发一种量表，用于评估老年冠心病（CAD）患者的压力状况，并检验该量表的有效性和可靠性。
初步量表的开发过程包括构建概念框架和初始条目、内容分析验证、语句修正以及预试验。本研究于2012年1月至2月采用问卷调查并进行一对一访谈的方式进行。研究对象为240名老年CAD患者。采用项目分析、因子分析、效标关联效度和内部一致性分析等方法对数据进行分析。
所开发的量表由32个条目和6个因子组成，分别为衰老与疾病（7个条目）、家庭关系（5个条目）、焦虑与退缩（9个条目）、日常生活管理（3个条目）、医疗方案依从性（4个条目）、贫困与经济（4个条目），解释了总方差的68.5%。该量表与韩国感知压力量表（KPSS）呈显著正相关。克朗巴哈系数为0.96，古特曼折半系数为0.91。
结果表明，老年CAD患者压力量表具有有效性和可靠性，是医疗卫生机构中评估老年CAD患者压力的适用量表。
